Summary

This study is a prospective assessment of the accuracy of ocular ultrasound as a tool to measure the diameter of the optic nerve sheath and the eyeball transverse diameter in healthy adult patients presenting to the Emergency Department and have confirmatory imaging of the optic nerve as part of their clinical care.

Conditions

  • Optic Nerve

Interventions

PROCEDURE

Ocular Ultrasound

1\. Patients presenting to the emergency department and have a normal head and/or ocular computed tomography scan will be considered for inclusion in this study. Study staff will discuss the study with the patient and obtain consent. At that point, operator will perform ocular ultrasound. Procedure will start with either the linear or microconvex probe. A single-use sterile gel packet will be used to apply gel to one closed eyelid. The probe will be placed with minimal pressure on the eye. A transverse measurement of the ONSD will be taken. In this same view the maximal transverse diameter of the eyeball will also be measured. Images of the eye with ONSD and ETD measurements will be captured. Repeat until three measurements have been obtained resulting in an average ONSD and ETD for that eye. Repeat for other eye. Switch probe and repeat on both eyes.
